Abstract

Introduction:

The emergency department is a high-pressure environment where rapid assessment and intervention can mean the difference between life and death. Vital signs, including blood pressure, heart rate, respiratory rate, temperature, and oxygen saturation, serve as primary indicators of a patient’s physiological status. ABG analysis, on the other hand, provides crucial insights into respiratory function, acid-base balance, and metabolic status. This study tried to analyze deaths over a year in an emergency department in a tertiary care centre and identify hemodynamic and blood gas parameters that could predict early death in ER.

Aims and objectives; 

• Analyze mortality patterns and their association with vital signs and arterial blood gas (ABG) parameters on arrival to the ER.
• Methodology: 

  This was a retrospective study conducted in the emergency department (ED) of AIIMS Patna over a one-year period ( Jan 1 , 2024 to 2025 ).

  Patients were categorized into two groups based on the time to death:

  • Early mortality: Death within six hours of arrival.
  • Late mortality: Death after six hours of arrival.

  Inclusion Criteria:

  All patients who expired in the ED during the study period.

  Exclusion Criteria:

  • Patients who were dead on arrival
  • Patients were transferred to the concerned departments or facilities before death.
  • Cases with insufficient medical records prevent data extraction
